摘要： 通过具体工程实例，对某矿山开挖山体岩质边坡进行了地质调查，对其稳定性进行了分析和评价；通过现场采取的岩样、尾矿砂样进行实验室化验得到的岩土参数，并用FLAC3D的模型计算，对开挖山体边坡的危岩掉块或滑塌提出了治理方案。

Abstract: Geological investigations on a rock slope near Boquan Iron Mine are presented in this paper. The investigations are performed on the rock slopes at the west side of the Pulverization Plant, south side of the Preliminary Broken Plant and Slopes from the Sieving Plant to the east side of the Preliminary Broken Plant. The stability of these slopes is evaluated and analyzed. The rock and soil parameters are determined from the laboratory testing on the samples from the rock slopes and the tailing mine.  The stability evaluation is also examined by using the FLAC3D finite element method. The mitigation methods are proposed for the potential problematic cutting slopes and rock falling areas.
